  • TextBox loses text when InvokeRequired == false

    - by Tom
    This is modified code I found on this site. When appending text to a TextBox and InvoveRequired is false the text will display in the box but the next time the function is called and InvokeRequired is true the text string placed by the first call is lost (""). Multiple calls when InvokeRequired is true work as expected. comBox is a type TextBox with multline = true. Any help would be appreciated. public void LogComText(string comText, bool newline) { if (comBox.InvokeRequired) { comBox.BeginInvoke(new Action(delegate { LogComText(comText, newline); })); return; } comBox.AppendText(comText); if (newline) comBox.AppendText(Environment.NewLine); }

  • How can you setup multiple WSGI apps on one server?

    - by Shakakai
    I'm working on a python based server product where a user can install WSGI-based python apps on their server. I can enforce any restriction on the application structure or format to make this easy. The user workflow would be: browse an app market, showing a list of WSGIpython apps select an app and choose "install" the app would be downloaded from a remote server to the user's server the http server would then have to be configured to start serving that application from the app's id, ex. a blog app with an id of "blog" at "/blog/", so all requests below /blog/ would be seen as root by the blog application. Any suggestions on how to set something like this up? Holler if my flow of consciousness lost you ;)

  • VB.Net HTTPWebRequest Speed is slow comparing Python URLOpen

    - by regexhacks
    Hi I am coding a web-crawler which will crawl the websites and selectively parse different sections of a web site. I am a .Net developer so the choice was obvious that I did it in .Net but the speed was very slow which included downloading and parsing of HTMLPages Then I tried to just download the contents first using .Net and then same domains using python but the python was very impressive in downloading data. I have achieved downloading using python but the later part is not that easy to code in python, which obviously i don't want to do. The same batch of domain which took 100 seconds in Python was taking 20 minutes in .Net based crawler I tried http://www.eqlit.com/ to download and in took 8 seconds in Python and same was taking 100 Seconds in .Net crawler Does anyone anyone have any idea why this is slow in .Net but fast in python?

  • Maintaining stored procedures in source control

    - by dub
    How do you guys maintain your stored procedures? I'd like to keep versions of them for a few different reasons. I also will be setting up cruisecontrol.net and nant this weekend to automate builds. I was thinking about coding something that would generate the create scripts for all tables/sprocs/udf/xml schemas in my development database. Then it would take those scripts and update them in source control every couple hours.... Ideally, I'd like to make this some sort of plugin/module for cruisecontrol.net. Any other ideas?

  • Can Fluent NHibernate be configured to use an arbitrary prefix on a property backing field?

    - by dommer
    I'm currently using a convention to (auto)map collection properties to backing fields in Fluent NHibernate. So, I map a property "Orders" to a field "_orders". The convention I'm using to do this is: public class HasManyAccessConvention : IHasManyConvention { public void Apply(IOneToManyCollectionInstance instance) { instance.Access.CamelCaseField(CamelCasePrefix.Underscore); } } Can I write a convention that maps a (collection) property to a field with a non-standard prefix (ignoring whether this is good coding practice for the present)? So, the property "Orders" would be mapped to "xyz_orders", for example. If so, how would I go about this?

  • What is a good standard for code width?

    - by BillyONeal
    Hello everyone :) I've heard in several places that it's bad to have code that is too wide onscreen. For example: for (std::vector<EnumServiceInformation>::const_iterator currentService = services.begin(); currentService != services.end(); currentService++) However, I've heard many arguments for 80 character wide limits. I'm assuming this 80 character limit comes from the traditional command prompt, which is typically 80 characters wide. However -- most of us are working on something much better than a typical command prompt, and I feel that using an 80 character limit encourages use of variable names that are far too short and do not describe what the variable is used for. What is a reasonable limit for a new project with no existing coding width standard?

  • Vista Basic theme ribbon issue

    - by Alain Rist
    Under Vista, when in Basic theme, after calling IUIFramework::Destroy() the Vista theme is lost, and enlarging the window does not display outside of the initial area. You can repro it easily with the SimpleRibbon SDK sample. In simpleribbon.cpp, insert in the WndProc switch block: case WM_KEYUP: DestroyFramework(); InvalidateRect(hWnd, NULL, TRUE); break; Compile, run, hit a key and try to enlarge in Vista Basic Theme (no problem in Win7 or Vista aero or Windows classic). How to work around? cheers, AR

  • MS Access caching of reports / query results

    - by FrustratedWithFormsDesigner
    Is it possible to cache a query or report the first time it is run? It seems that opening a report will re-query the datasource. For certain queries, the data source does not change frequently enough that I'd be worried about a cache being out of date (users are notified when the database changes), and it would be much easier for the users to be able to open the report instantly rather than having to wait several minutes every time they want to see the data (though I realize if they close the file the caches will be lost - that's OK). Data comes from an ODBC connection to Oracle, using Access 2003.

  • javascript not working on localhost

    - by Adam McMahon
    Ok so I'm lost here, frustrated and pulling my hair and out. Plus probably about to be fired or take a pay cut. I moved Files from a development server to my local machine. The files are consistent (used diff tool), all the dependencies are there. It works for the most part. The problem is that the some of the javascript (not all) is just not working. We're using jquery and a lot of plugins for it. I've checked with the web developer plugin in firefox and all the js files are loading. I cleared the cache in both firefox and chrome multiple times to no avail. The development server is a windows server running wamp. My local machine is running ubuntu. Somebody tell me what I missed.

  • Why are items being placed below?

    - by Adam DePolo
    This is really confusing and I have never had this occur. For my computer, it is fine. But for anyone else's computer I have tried, it screws up. So on my site, designatease.com , the second bar down, it places the fifth item down below the first four. I am not sure why it is doing this. I want them to span across the bar but the stop at about half way. Help me out SOF.

  • Error with global variable in php not extending to included php file

    - by phileaton
    I have an html file that calls has a php section in the header like so: $page = basename($_SERVER['PHP_SELF']); Now further down in the html file I have a included footer like so: <?php include("footer.php"); ?> In this script I am referencing the $page variable, but it doesn't find it. I tried echoing the variable and nothing happened. When I place the basename() code in the footer.php file though, it handled it fine. I'd like to be efficient with the coding, so how can I get the footer.php file to get that $page variable? Is there a better way to do this than including the $page variable twice?

  • Where does one enter the JavaScript code in CRM Dynamics?

    - by Konrad Viltersten
    I've started to play with CRM Dynamics yesterday so this question should be seen as a very basic one. I've been coding for many years but CRM D is news to me. Apparently, one is supposed to be able to enter JavaScript code to customize the behavior of the application. I've understood that there's an API for that and that touching DOM directly or playing with jQuery is a no-no. Question: Where is the JS-code supposed to be entered? I've gone through all the menus but as far I can see, there's no spot where I could plug-in my custom code. E.g.: Where do I get to define a validation for the last name of a contact currently being defined?

  • iPhone MVC Question

    - by HM1
    Hi, I'm bit of a newbie and had a basic question regarding adhering to the MVC model in iPhone coding. How do I setup a Model class that holds my data and connect it to different controllers in the following setup: Using Interface Builder, I created a tab controller in which - Tab #1 has a Nav Controller and a hierarchy of View Controllers. - Tab #2 has a View Controller So with what I have now, the View Controller under Tab #1 alloc init's the model class and I know how to pass the model from one ViewController to the next in the Navigation Hierarchy where it can pass the data and/or be updated with new data. Question is how to pass it from Tab #1's View Controller to Tab #2 View Controller as there is no code linking the two??? Thanks in advance, Hiren.

  • How to Create an Array from a Single Variable and Form Multiple Foreach Loops?

    - by matphoto
    I'm fairly proficient in HTML/CSS, but very new when it comes to the likes of PHP and Javascript. I've jumped headfirst into coding Wordpress shortcodes (basically php functions), and so far, through trial and error and seemingly endless browser refreshes, I've been able to figure everything out. I just hit a huge wall though, hence why I'm here. Basically, I'm trying to give an attribute a list of values like: attr="23, 95, 136, ect" The function then needs to take that attribute variable and create an array with it: $arr = array($attr); To me that seems as if it would work, but the array takes the whole list as one value instead. After doing that I want to create a foreach loop that parses each number from the list, possibly through yet another foreach loop if possible, and returns a section of code for each one, and I'm not quite sure how to pull that off either. Any feedback would be greatly appreciated.

  • Which Subversion do I install for Windows?

    - by johnny
    I was reading this article on Coding Horror: http://www.codinghorror.com/blog/2008/04/setting-up-subversion-on-windows.html I went to the downloads and am confused. I would have just downloaded the first entry but I am afraid it would break my server or something if I don't have apache. We use IIS only and I wouldn't want to break it somehow. I don't even need a web or webdav front end. Which one should I install on this page, please: http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91 thank you for any help. edit: thanks for information, but I am hoping to stay free with the "regular" subversion. I plan on using TortoiseSVN for the client.

  • A way of allocating multidimensional arrays dynamically

    - by C77431
    salute.. I am learning dynamic allocations for multidimensional arrays in a book and I found some ways for that, And now haven't problem in it. But the author of the book shows us a way, but it doesn't work correctly. It is this: pbeans = new double [3][4]; // Allocate memory for a 3x4 array And this is the error: error C2440: '=' : cannot convert from 'int (*)[4]' to 'int *' how should i define pbeans ( if this type of coding is legal)? and what is the problem exactly? Regards.

  • .Net Round-trip Types

    - by Fujiy
    I making a method that generate a unique string key for some parameters. But the same key if call with same values. I just accept primitive types, string, DateTime, Guid, and Nullable(since I append types together, I can distinguish who is int and who is int?), because I can convert all to string without lost values or precision.(for float and double a use ToString("R"), to DateTime ToString("O")). Exists a easy way to know which types I can transform in strings without conflict? And how do this transform(how I said before, float, double and datetime have specific ways) Thanks

  • Finding the heaviest of N objects using M scales

    - by cpprulez
    We have N objects and M scales. It's up to us what the objects are, and we need to position the objects on the scales so that it is undoubtful which is the heaviest object. For example, if we have 3 objects: "a", "b", "c" and 2 scales, one possible solution is "a" "b", "b" = "c" (here "a" is the heaviest). I need an algorithm which generates such solutions given N and M. Also let's assume that "a" is always the heaviest object. I've lost a few hours figuring out how to do it, but no matter what I figure out, there's always cases which I miss. For example, another solution is: "a" + "c" = 2 * "b", "a" "c".

  • Do most web 'programmers' (not designers) use WYSIWYG editors or hand code their HTML?

    - by John MacIntyre
    When I started programming web pages, it became immediately obvious that the WYSIWYG editors sucked. The HTML output was difficult to maintain, did things in ways you may not have agreed with, completely messed up existing pages if opened, couldn't handle code in the page, and was polluted with dead or irrelevant code like <font ...></font>. At that time, I didn't know a single programmer with more than 6 months experience who didn't hand code their HTML. Even now, most of the developers I know hand code their HTML. But, I also realize this was a decade ago, WYSIWYG editors have improved, and I may be seriously underproductive hand coding my HTML. Do you, as a web programmer, use WYSIWYG editors for your HTML? PS-I'm kind of thinking we can just vote either YES or NO, and put comments below.

  • gVim and multiple programming languages

    - by Abhi
    My day job involves coding with Perl. At home I play around with Python and Erlang. For Perl I want to indent my code with two spaces. Whereas for Python the standard is 4. Also I have some key bindings to open function declarations which I would like to use with all programming languages. How can this be achieved in gVim? As in, is there a way to maintain a configuration file for each programming language or something of that sort?

  • Better understanding of my SQL transactions

    - by Slew Poke
    I just realized that my application was needlessly making 50+ database calls per user request due to some hidden coding -- hidden in the sense that between LINQ, persistence frameworks and events it just so turned out that a huge number of calls were being made without me being aware. Is there a recommended way to analyze individual transactions going to my SQL 2008 database, preferably with some integration to my Visual Studio 2010 environment? I want to be able to 'spy' on individual transactions being made, but only for certain pieces of my code, and without making serious changes to either the code or database.

  • two classes contain objects of each other

    - by Julz
    hi, i hope there's a simple answer to this. without getting too complicated i have two classes. an "Animal" and a "Cell" Cell contains an Animal as a member. Animal has methods that accept Cells in their parameters. i'm just confused as to how i #include each class the others header? i've only ever had to go up a chain of classes and just included the last class header in the next and so on, but this circular situation has me a bit lost. i hope that makes sense, any help greatly appreciated.

  • Server RAID 5 failed...all I have left is my compiled website

    - by David Murdoch
    Yesterday, 2 of the 3 drives in my dev server's RAID 5 decided to die on me (with no warning). I've come to grips with the fact that my data is most likely lost unless I shell out some major bucks for professional data-resortoration. People, don't be an idiot like me and treat your RAID as a data backup! Luckily I published the site about 4 hours before my files went bye-bye. Is there any way to run some [magical] program to restore my compiled site to their original files? Also: I develop on one machine with the files stored on the server...is there some visual studio 2010 web cache on my local machine (the one that didn't crash) that I may be able to use?

  • Is Microsoft CCR gaining any traction?

    - by spender
    Microsoft's Concurrency and Coordination Runtime quite literally saved a project that was running into major issues with deadlocking. Since then I find that I use it more and more frequently for almost anything that requires asynchronous coding producing results that run lighter and faster than before. I can honestly state that it has transformed the way I think about multithread/multicore dev. Despite my personal love for CCR, there appears to be very little buzz surrounding it on the web and was wondering if anyone can offer any reason for this. Are there better alternatives, or is it a lack of promotion from MS, or are people simply happy with the existing tools?

    Hey, i am coding a small php forum from scratch and would like to show readers what posts he hasnt read yet and what forum categories have unread posts since this visit, pretty much how phpbb or invision boards work. How do i approach this, cookies? phpbb doesnt seem to use cookies for this, not very a good idea do have a cookie for each post... maybe use css visited attribute? but i dont see how would that work if a new post pops up. Thanks.
